The following code does the same as EXECSCRIPT but don't generate an error in case of errors during compilation of the code. However, it still may generate runtime errors.

lcTempName = ADDBS(SYS(2023)) + SYS(2015)
STRTOFILE(lcMycode, lcTempName + ".PRG")
COMPILE (lcTempName + ".PRG")
IF (lcTempName + ".ERR")
   * Error in the code
ELSE
   DO (lcTempName + ".FXP")
ENDIF
ERASE (lcTempName + ".*")
